Dentists and cross-infection.
A structured questionnaire was administered to a random sample of general dental practitioners in Natal, South Africa in 1994, to ascertain the precautions they use against cross-infection and to gauge the attitudes and behaviour towards the treatment of HIV-infected individuals. An interview was conducted covering 5 broad topics: demographic details, personal barrier protection, instrument sterilization and disinfection, sharps disposal and incidence of needlestick injuries and the extent of the knowledge, attitude and behaviour of the practitioners toward the treatment of HIV-infected individuals. The key findings were: routine glove wearing, for all patients, was practised by 87 per cent. The most common heat sterilization method was by autoclave (68 per cent), although a dry heat sterilizer and water boiler were used by 22 per cent of the respondents. Of the 18 respondents reporting a needlestick injury in the past 6 months only one sought after-care. 42 per cent of the respondents would continue to treat carriers of HIV in their practices. This survey shows that a significant number of dentists are using unacceptable cross-infection control procedures. Educational efforts should be made to improve their knowledge and to alleviate anxiety of health workers to treat HIV-infected patients.
